On September 9, 2013 a Mack truck pulling two trailers was westbound on Oregon Highway 31 when the driver reportedly fell asleep as he approached the Highway 97 junction, where there are two yellow traffic signs and a flashing yellow light warning drivers to stop ahead.
The truck and trailers traveled off the north shoulder on Highway 31, where the driver awoke and over-corrected as he tried to steer back onto the road. The truck and trailers overturned and slid through the intersection where the truck crashed into an ODOT sign before coming to rest. The driver was cited for Careless Driving and Failure to Obey Traffic Control Devices.
Because driver fatigue is one of the leading causes of truck accidents, there is a daily and weekly limit on the amount of hours a driver can be on the road, and drivers must maintain logbooks to keep track of those hours. Although trucking companies must monitor closely their employees’ hours of service, they often put pressure on drivers to ignore the law and quickly deliver the load.
